Roland Lorenzo Mitchell seeks to appeal the district court’s denial of his motion to suppress evidence discovered by officers of the New Mexico Department of Public Safety during a warrantless search of the tractor-trailer he was driving at a border checkpoint. Recognizing that his notice of appeal was untimely, Mitchell filed a motion for an extension of time with the district court arguing that the delay was the result of excusable neglect under Federal Rule of Appellate Procedure 4(b)(4), which was granted. The only grounds identified by Mitchell’s counsel in justifying the delay was counsel’s heavy work load and involvement with other matters. Because we conclude that these justifications do not constitute excusable neglect as a matter of law, we hold that the district court abused its discretion in granting Mitchell’s motion for an extension of time. On that basis, we DISMISS this appeal for lack of jurisdiction.

Mitchell, a long haul driver, was arrested at the Port of Entry in Lordsburg, New Mexico (“POE”) when New Mexico De *1150 partment of Public Safety officers operating the POE discovered cardboard boxes containing a large quantity of marijuana in the tractor-trailer he was driving during a warrantless search. Arrested, Mitchell was charged with possession of more than 100 kilograms of marijuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1) and (b)(1)(B). Mitchell filed a motion to suppress the marijuana found in the truck claiming that the search violated the Fourth Amendment. When the district court denied his motion, Mitchell entered a conditional guilty plea, reserving his right to appeal the district court’s denial of his motion to suppress. He was sentenced to 60 months’ imprisonment.
Judgment was formally entered on February 9, 2005. A notice of appeal was filed on February 25, 2005, six days after the ten-day period for filing criminal appeals set forth in Federal Rule of Appellate Procedure 4(b)(1) had expired. As noted above, recognizing that his notice of appeal was untimely, Mitchell filed a contemporaneous motion seeking an extension of time to file his notice of appeal. The motion stated that the delay was caused by his counsel’s heavy work load and involvement with another trial. The district court granted the motion in a summary order that contained no reasoning or explanation.

We review a trial court’s decision extending the time to file a notice of appeal for abuse of discretion.
City of Chanute v. Williams Natural Gas Co.,
“A court of appeals acquires jurisdiction of an appeal only upon the filing of a timely notice of appeal[;] this requirement is mandatory and jurisdictional.”
Gooch v. Skelly Oil Co.,
Historically, we have held that a party’s untimely filing is not the product of excusable neglect when the delay results solely from counsel’s busy practice. For example, in
Buckley v. United States,
Since our decision in
Buckley,
the Supreme Court has directly addressed the meaning of excusable neglect. In
Pioneer Inv. Servs. Co. v. Brunswick Assocs. Ltd. P’ship,
Adoption of the four-factor approach outlined in
Pioneer
does not change our conclusion that the failure to file a timely notice of appeal as a result of counsel’s involvement with other matters or heavy work load is not excusable neglect. Guiding this analysis is our decision in
United States v. Torres.
There, the defendant filed his notice of appeal eight days late, and filed a subsequent motion for an extension of time explaining that the delay resulted from his counsel’s confusion regarding filing deadlines.
*1152 In applying the Pioneer factors to the present case, three of the factors weigh in favor of allowing Mitchell’s untimely filing. The delay was very short, no prejudice has been identified by the government, and there is no evidence that indicates the delay was attributable to bad faith on the part of Mitchell or his counsel. Indisputably, however, counsel’s stated reason for the untimely filing is that he was “immersed” in work for another trial in the days leading up to the filing deadline. This type of neglect is not excusable under the law of our circuit and trumps the other three. Unless we are prepared to hold that whenever a lawyer is busy, and in trial, the rules on filing a notice of appeal may be set aside, we have no alternative but to reject defendant’s plea. Not inclined to deliver such a pronouncement, we hold that the circumstances before us do not, as a matter of law, present a case of excusable neglect. 2
Ill
Accordingly, we DISMISS this appeal for lack of jurisdiction. 3
Notes
. "Good cause” arises when the timely filing of a notice of appeal was prevented by conditions outside the control of the party responsible for the delay.
See United States v. Torres,
. Other circuits have adopted an equally strict view of excusable neglect in the context of attorney inadvertence both in cases predating and following the Supreme Court’s decision in
Pioneer. See Deym v. von Fragstein,
. Our holding today does not preclude other post-conviction proceedings.
